Urg so close. Thought it was a trivial change, so didn't bother
retesting the binding. I think I have it right now...

  compatible:
    oneOf:
      - items:
          - enum:
              - brcm,bcm72165-asp
              - brcm,bcm74165-asp
          - enum:
              - brcm,asp-v2.0
              - brcm,asp-v2.1

Something like this look good? Will submit a v5 tomorrow.

Thanks,
Justin
